My post about oiling the motor was just for general knowledge . Not saying that it was relevant to your situation specifically .Mine was showing 4kohm resistance after shooting out smoke and crackling..
All fixed replacement motor #3 was the winner.
Not a hvac guy but even an honest one who would have just fixed what was wrong would have probably ran me over $1000+
a non-honest one would sell me a new unit.
My cost besides my time was about $200
